# UncaughtTypeError: FUI.select is not a function

 * Every page of my site throws these errors only when Forminator and Popup Maker
   are both activated. (Using 2020 theme with NO other plugins enabled). Also when
   both Forminator and Popup Maker are both activated and these UncaughtTypeErrors
   are happening, the date picker in The Events Calendar won’t pop up. We are also
   having a lot of trouble getting our Forminator forms to pop up in general. Much
   of the time there is a beep but no form pops up and users have to click a bunch
   of times, try ESC, reload page, etc. Getting a form to pop up on our About>Contacts
   page is random luck though the ones near the top of the page work much better
   than those near the bottom.
 * Here is a bit of the error listing from my browser console (shows up in Firefox
   and Chrome):

 * Hi [@kengholm](https://wordpress.org/support/users/kengholm/),
 * Could you give us a bit more information on how the setup is being done on your
   site.
    Is the Form inside a Popup? Where is the event datepicker shown, on event
   page or you’re embedding your events elsewhere? How is the Event set up to show
   the date picker? Or any other info that could help us replicate this.
 * Do note that Forminator is not tested with Popup Maker so it’s possible that 
   a specific setup can cause conflicts between plugin scripts.
    You could try using
   the form within in our Hustle popup plugin and see if your setup works that way:

 * Sorry I didn’t get back to you promptly. I’ve been continuing to work on this
   but didn’t find the true source of the errors and we decided to turn off popups
   for now. I’m going to enter a new topic for the conflict between The Events Calendar
   date picker and the Forminator date picker.
    Thank you.
